Destodur re, zvakare anozivikanwa seCASI 2422-91-5, ishandare yaishandiswa uye yakashandiswa zvakanyanya. Nekuda kwekuita kwayo kwakanaka uye zvakanakira, zvakave zvinoshandiswa zvakanyanya mumaindasitiri akasiyana siyana. Munyaya ino, isu tinoongorora mashandisiro ezvekushandisa dedomito uye tsvaga kuti nei zvichikurudzira nevanogadzira.
Destodur re ndezvemhuri yezvinonhuwirira diisocyanates, mishonga yakashandiswa zvakanyanya mukugadzirwa kwejasi rePolyurethane, anomisheni uye elastomers. Iyo yero yakajeka ye amber mvura inosanganisira musanganiswa weShokowo nemakemikari akafanana emakemikari. Iyo yakakosha ingano yeDermodur re is toluene diisocyanate (TDI), iyo inoshandiswa zvakanyanya mukugadzirwa kwePolyurethane foam.
Imwe yemashandisirwo eDemodur reiri mugadziri yeiyo polyureurethane machira. Polyurethane Coatings inopa dziviriro yakanaka kubva kuCorrosion, mamiriro ekunze uye abrasion. Ivo vanozivikanwa nekuda kwekusimba kwavo kwakanyanya uye kuita kwakanaka munzvimbo dzine hutsinye. Destodur re ndeye yakakosha chikamu mune aya ekubatanidza mafambiro, achivapa kuwedzera kuomesa, kuderedza uye kurwisa kwemakemikari.
Kumwe kushandisirwa kwakakosha kweDermodur Re ndiko kugadzirwa kwePolyurethane anomiririra. MaPolyurethane anomiririra anoshandiswa zvakanyanya mumotokari, kuvakwa nezviramir zvedhipatimendi nekuda kweshamwari yavo yepamusoro uye kuwanda. Destodudur Re inokwidziridza kusungwa kwesimba rePolyurethane anomisheni, achiivabvumira kuomerera kune akasiyana siyana simbi, mapurasitiki uye huni. Izvi zvinovaita kuti vakwanise kuomesera, kusungwa uye kusungwa zvinoshandiswa.
Destodur re inoshandiswawo mukugadzirwa kwePolyurethane Elastomers. Polyurethane Elastomers anoratidzira zvakanakisa manhamba akadai sekukwira kwakakwirira, kubvarura uye kupokana uye kupokana neabrasion kuramba. Ivo vanoshandiswa mumaindasitiri akadai setsoka, automotive nekugadzira maindasitiri. Destodur reer inoita basa rakakosha mune synthesis yeaya elastesmers, achivapa zvine simba rakanakisa simba uye elongation zvivakwa.
Uyezve,Demodur reinozivikanwa nekuda kwekurapa kwayo kupora. Izvi zvinoreva kuti inogona kukurumidza kuyambuka-chinongedzo nePolyols kuti iite yakasimba polyurethane network network. Kuporesa nekukurumidza kunonyanya kudiwa mumaindasitiri ayo anoda nekukurumidza nguva dzekutendeuka, dzakadai semaindasitiri emotokari kana ekuvaka emaindasitiri. Mukuwedzera, dedomitur rekuenderana neyakajeka nehuremu hwakawanda hwe polyols, anogonesa vagadziri kuti vagadzirise zvinhu zvezvigadzirwa zvavo kune izvo zvinodikanwa.
Mukupedzisa, dedomitur re (Cassi 2422-91-5) Icho chinoshandiswa zvakanyanya zvinoshandiswa mumaindasitiri akadai sejasi, anomisheni uye elastomers. Zvivakwa zvaro zvakasarudzika, kusanganisira kuomesesa kuomesa, kudenha uye kupora nekukurumidza, ita sarudzo yakakurumbira pakati pevatariri. Kunyangwe ichivandudza kudzivirirwa kwekushatisa kuburikidza nePurestethane Coatings, kuwana zvisungo zvakasimba muzvinoshatisa, kana kuwedzeredza zvimedu zvemakwenzi, demodur reziru zvakaratidzwa kuve chinhu chakakosha mukugadzirwa kwezvinhu zvakakwirira.
